Is there someone out there with the greddy setup and jim's starion intercooler and pipings that can help me pick out what size couplers i need? i'm probably going to order them from atp, but i want to make sure i get the right ones. as of right now, i don't have any couplers, so need the sizes for turbo to afm, turbo to pipe, pipe to intercooler on exhaust side, intercooler to pipe in intake side, and pipe to intake manifold. I think that should be it, right?

I literally answered this just yesterday.
There is also some info in the greddy archive.

I'm getting my couplers from Pat @ Forge. Good prices.
